This Phase II study is open to patients with metastatic colorectal cancer who have tried but failed chemotherapy regimens containing oxaliplatin and irinotecan. Patients must not have received anti-EGFR (Epidermal Growth Factor Receptor) treatment (for example, cetuximab, panitumumab) in the past. Patients with wild-type KRAS (v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog) colorectal cancer will be randomised to receive either BIBW 2992 or cetuximab. Patients with KRAS mutated colorectal cancer will not be randomised, but will all receive BIBW 2992. The main objectives of the study are: to compare the effectiveness of BIBW 2992 with that of cetuximab in patients with KRAS wild type cancer, and to assess the effectiveness of BIBW 2992 in patients with KRAS mutated cancer.

An Open Label, Partially Randomised Phase II Study to Investigate the Efficacy and Safety of BIBW 2992 in Patients With Metastatic Colorectal Cancer Who Never Received Prior Anti-EGFR (Epidermal Growth Factor Receptor) Treatment

PFS time is defined as time from randomisation (wild-type group) or start of treatment (mutated group) to tumor progression evaluated according to RECIST (version 1.1) or death whichever occurs earlier. Median and confidence interval estimated using product-limit Kaplan-Meier method.

OS time is defined as time from the date of randomisation (wild-type group) or date of start of treatment (mutated group) to the date of death. Median and confidence interval estimated using product-limit Kaplan-Meier method.

Pre-dose Concentration of Afatinib in Plasma at Steady State on Day 8 (Cpre,ss,8) [ Time Frame: day 8 ] [ Designated as safety issue: No ]

Cpre,ss,8 represents the pre-dose concentration of afatinib in plasma at steady state on day 8.

Biological treatment (including Bevacizumab or any other antiangiogenic agents) during the trial is not allowed.

Known pre-existing interstitial lung disease.

Planned major surgical procedures during the trial period.
